`JOSEPH `Nason Ann JOSEPH F. WILSON, or BOSTON;V ivL-tssttcuusnrrs. I Letters Patel-nt Zlio. 68,306., dated August 1867. I l I l mrsovsn' GATE ros RAILROAD c sos'stuesj TO ALL WHOM IT MAY CONCERN: v

, Be it known that we, JOSEPH NASON and JOSEPH F. W'ILSON, both of Boston, in the county of Suffolk, and State of Massachusetts, have invented an improvement in'Operating Gates atRoad-Crossings; and we do 'her'.eby declare that the following, taken in Connection with the. drawings which accompany and form part of this specification, is a description of our invention suiicient to enable those skilled in the art to practise it.

In opening and closing the gates where railways cross highways at grade, the means'that haveloeen herel tofore employed to simultaneously operate gates on opposite sides of the highway are expensive, and generally require the attention 'and lai ofious manipulation of several gatemen. Y

Our invention' is designed to remedy these difficulties, by mounting the several gates on tubular shafts, through each of which und the gate a stationary post runs, the shafts extending below the track-way, and-having at or near the lower end of each a pulley or Wheel, around which a rope or chain passes in su'ch'manner as to bring the several shafts into a. train operated by said rope, 'so that by opening enclosing either gatethe others will be thereby simultaneously opened or closed, or by operating a `lever connected with a chain or rope, all the gates shall be operated. together'. v 'l f It is in this connection of the gates together, below the track, so that all are simultaneously thrown open or shut,l that the invention consists. 1..

The drawings .represent e-set of `gates connected and"opor-ated in accordance without invention, A show? ing a plan, and B a cross-section between thelga'tes. au. b b( denotetwo sets or pairsot: gates, one pair bei-ng upon one, and the other upon the opposite side of the road-across `which-the rails c run.k -Each gate `swings on a stationary vertical post, cl, and is fixed upon the top of a sleeve or'tubular shaft, e,.(through which the post extends,) said shaft extending belowthe track or road-bed, and having fixed upon its lower end a pulley or vfheehf, the several wheels being connected or mad-e intoa train byY a band, rope, or chain, g, engaging with encinas seen at A, guide-pulleys h being fused, if desirable, to force the band into contact with the Wheels or pulleysf. At any convenient point the rope or chain g is attached to one end of'a lcverptz, whose opposite end is so located'as to be within reachtof the gatoman, so that 'by swinging the level' in one O1' the other direction, he actuates the chain, and siufultaneously opens all or closes all the gates. The same result may, however, be obtained by swinging either one of the gates, this operation correspondingly swinging all the others. In most cases alchain and 'chain-pulley may preferably be used instead of a rope and plain.v groove pulleys to connect and operate thegates, the teeth of the pulleys working into the links of the .chain and insuring proper relative movement ofl all the gates. lustead of having the tubular shafts Or sleeves `e to rotate on the posts d, these sleeves may be made stationary, and the pulleys and gates be fixed upon the posts, but we prefer the arrange ment substantially as shown, as most conducive to strength and ease of operation. The pulleys and connecting apparatus being arranged in a box below the track, are protected from the injurious eifects oi' open exposure to the weather, and may be kept in much better operating conditionl than where high posts are used with pulleys and overhung Yconnections from post to post to operate the gates.'

We.claim the combination of the rotary gates, supporting shafts or sleeves, and their pulleys and connecting band or chain, with reference to the stationary posts, and relatively tov each other, the pulleys and their operating mechanism being arranged below the track or road-bed, and operating together to simultaneously open or close the gates, substantially as set forth.

J. F. WILSON.
